Chemical Structure

1-(2-Butoxyethyl)-3,5-dimethyl-1h-pyrazol-4-amine CAS 1251330-51-4 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

1-(2-Butoxyethyl)-3,5-dimethyl-1h-pyrazol-4-amine (CAS 1251330-51-4) is a high-purity analytical reference standard with the molecular formula C11H21N3O and a molecular weight of 211.30 g/mol.

The molecular framework of 1-(2-Butoxyethyl)-3,5-dimethyl-1h-pyrazol-4-amine (C11H21N3O) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 1-(2-Butoxyethyl)-3,5-dimethyl-1h-pyrazol-4-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
